Abstract : The report describes the second of four test series done to develop a probabilistic, physics-based model for the fragmentation of building faade components subjected to airblast. The primary objective of this second test series was to measure the response of full-scale samples to relatively long duration, low pressure loads produced by a large explosively-driven shock tube. In three glass window tests, the fragment size and velocity distributions were estimated using rear-view and side-view high-speed video; a Weibull size distribution obtained the best fit. In a concrete masonry unit (CMU) wall test, the fragment size was estimated using physical collection; a power law size distribution obtained the best fit.
